%0 Journal Article %T On strong approximation by modified Meyer-K"onig and Zeller operators %A L. Rempulska %A M. Skorupka %J Tamkang Journal of Mathematics %D 2006 %I Tamkang University %R 10.5556/j.tkjm.37.2006.123-130 %X We introduce certain modified Meyer-K"onig and Zeller operators $ M_{n;r} $ in the space of $r $-th times differentiable functions $ f $ and we study strong differences $ H_{n;r}^q(f) $ for them. This note is motivated by results on strong approximation connected with Fourier series ([7]). %U http://journals.math.tku.edu.tw/index.php/TKJM/article/view/156
